Abstract: An integrated circuit (IC) module comprising at least one memory mapped resource, at least one port arranged to be coupled to a further IC module, and an address decoding component. Upon receipt of a resource access request by the IC module, the address decoding component is arranged to extract at least one position parameter from an address field of the received resource access request, determine if the at least one position parameter indicates a target resource as residing within the IC module, and if it is determined that the at least one position parameter indicates the target resource as not residing within the IC module, modify the at least one position parameter to represent a change of one position and forward the resource access request with the modified position parameter over the port to the further IC module.

Abstract: An interrupt controlled prefetching and caching technique includes transferring peripheral data from a peripheral to a peripheral cache via direct memory access in response to receiving an interrupt request from the peripheral. The technique includes executing an interrupt service routine prologue in response to completion of transferring of peripheral data. The technique may include providing a base address and a transfer trigger to initiate the transferring of the peripheral data. The technique may include executing a peripheral interrupt service routine after executing the interrupt service routine prologue. The technique may include executing an interrupt service routine epilogue after executing the peripheral interrupt service routine, the interrupt service routine epilogue including resetting an interrupt status flag associated with the interrupt request.
